Welcome to SAOimage: The Next Generation (1.9)

SAOtng is the new and improved version of the popular SAOimage display
program. It also is a superset of the ximtool program developed at NOAO
for IRAF and as such, utilizes the NOAO widget server (included in
this package). It also incorporates the X Public Access mechanism
(XPA) to allow external processes to access and control its data, GUI
functions, and algorithms. SAOtng supports direct display of IRAF
images and FITS images (and easily can support other file formats),
multiple frame buffers, region/cursor manipulation, several scale
algorithms, many colormaps, and easy communication with external
analysis tasks. It is highly configurable and extensible to meet the
evolving needs of the astronomical community.
